Question about Brother MFC 420CN All-In-One InkJet Printer
How do I clean a clogged print head? My faxes come out in a purple color, but when I try to print of my computer nothing that is black shows up. I the problem is where the ink is dispensed into the printer itself not the cartridge. Is there any way to flush it out if it already clogged or dry? What can I do?
The ph will be cleaned by pressing ink thru the system (tubes and ph). Do use only dye-ink for this procedure. The best way is to use original brother ink.
place a new cart into position and make sure that they are secured.
press menu then start bk copy then fortimes arrow up. machine will be in maintenance mode. press 7 then 6 then 4 then start bk copy. machine will refresh ink and do some cleaning. afterwards press 7 then 6 then 3 then start bk copy. machine will do a power purge. when finished press 9 then 9 to leave the maintenance mode. do run a test quality print by pressing ink etc.. If you cant see any bk the ph is defenetly clogged and cant be fixed anymore. It needs replacing.
